We though the flavors were fantastic. The only real change I made was to use fresh Mandarin oranges & juice instead of grapefruit. My pork was leftover grilled tenderloin so I just briefly warmed it with the ginger, then added the hoisin sauce. I used Trader Joe's brown jasmati rice because it has such great flavor. The recipe doesn't call for baby bok choy but I assume they mean that. I had only the large bok choy so I chopped the bottoms and tops separately, started with the bottoms, then added the tops, then the liquids.
Great recipe. I followed the directions exactly and this has a nice fresh flavor! The grapefruit seems a bit weird but was a great touch and is very refreshing.
